Actress and vegan diet enthusiast Alicia Silverstone has a strange way of feeding her 11-month-old son Bear Blu. In a video posted on her healthy living website thekindlife.com, Silverstone chews a bite of food and then passes it straight into her little boy’s mouth mama-bird style.

“I just had a delicious breakfast…” writes Silverstone introducing the video, “I fed Bear the mochi and a tiny bit of veggies from the soup…from my mouth to his. It’s his favorite…and mine. He literally crawls across the room to attack my mouth if I’m eating.”

Though pre-chewing babies food is common cultural practice around the world, especially in underdeveloped countries where people might not have access to modern conveniences such as blenders, not everyone thinks it’s a healthy idea.

Speaking with Fox News, Dr. Jennifer Landa, M.D., Chief Medical Officer of BodyLogicMD warned, “Various viruses and bacteria, but especially herpes virus, may be passed from mother to baby.” She added, “These microbes present a challenge that the infant’s immune system may not be ready for.

Comments on Silverstone’s website are generally positive about her quirky way of giving Bear Blu his breakfast. “That’s so precious and bear looks so happy!” wrote one fan. “I am sure this is a way to ward against picky eater in your future!!” added another. Mira Jacob, deputy editor of the parenting website Babble.com isn’t quite so enthusiastic: “A lot of moms chew a portion of their baby’s food; it’s often a very natural transition,” she told Fox. “But this just looks really funny, like Alicia is making out with her son.”
